We look at the division of 308310 by 11 
The aim is to understand the frequency of 11 in 308310.

Let's proceed to step 1:
The number 11 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 11

Advancing to step 2:
If we divide 30 by 11, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 22 away from 30, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 11

Let's proceed to step 3:
The number 11 fits into 88 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 88 from 88 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 11

Moving on to step 4:
If we divide 3 by 11, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 11

Let's proceed to step 5:
11 can be fit into 31 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2802.0
Subtract 22 from 31 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 11

Advancing to step 6:
If we divide 90 by 11, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 28028.0
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
11 goes into 20 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 28028.1
Deduct 11 from 20 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
If we divide 90 by 11, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28028.18
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
11 goes into 20 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 28028.181
Deduct 11 from 20 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
11 goes into 90 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28028.1818
Deduct 88 from 90 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
20 divided by 11 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 28028.18181
If we subtract 11 from 20, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
90 divided by 11 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 28028.181818
Deduct 88 from 90 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
20 divided by 11 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 28028.1818181
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
The number 11 fits into 90 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 28028.18181818
Deduct 88 from 90 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 28028.18181818 with a balance of 2e-09.
